We use a number of statistical distributions in Statistical Quality Control. The ________
distribution is considered fully described, meaning that you only have to know a single
parameter - the mean - in order to know the standard deviation because the standard
deviation is the square root of the mean. - Answer -Poisson
Which PON indicates that natural numbers starting with first digits are not distributed
equally? - Answer -Benford's Law
In business practice, a process may be statistically in-control but may not be in the
range that the firm would desire in terms of high quality. That is to say, a process may
be in-control but not be in a desired state. - Answer -True
, The Taguchi Loss Function was used by Ford to evaluate the impact of quality-related
defects on the company's bottom line. By applying the function, Ford was able to
identify the most critical quality parameters and optimize its production processes to
minimize the loss due to poor quality. The application of the Taguchi Loss Function
helped Ford to improve the __________ of its products, reduce costs associated with
poor quality, and increase customer satisfaction. - Answer -Reliability
The sharing _________ refers to a system of economic activity where individuals can
share resources, such as goods and services, with one another. This is often facilitated
through online platforms, such as websites and mobile apps, that connect people who
have resources to share with those who need them. - Answer -economy

of goods and services. Operations managers must ensure that these facilities and
equipment are well-maintained, efficient and meet safety regulations - Answer -Plant
Operations managers must monitor and measure the performance of the organization's
operations, and take action to improve performance as needed. This includes analyzing
data to identify areas for improvement, setting performance targets and monitoring
progress towards achieving them. - Answer -Performance
___ __________ often focus on setting direction, and the larger goals of the

the organization within specific structures, rules, guidance, or policies. - Answer -
